'ro ALL WHOM 1T MAY OONCERN: Y Be it known that I, C. 0. GARDINER. of' Springfield, in-the county of Clark, and State of Ohio, have invented certain new and useful Improvements in Grain-Drills; and I do hereby declare that the following is a.

full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, and to the letters of reference marked thereon, like letters indicating like parte wherever they occur. I l

To 'enable others skilled in the art to construct and use my invention, I will proceed to describe it.

. vMy invention consists in certain improvements in the construction of the feedingeylinders and cups used in grain-drills, as hereinafter explained.

Figure 1 is a transverse vertical section,`taken on the line z-x of g. 2.

Figure 2 is a longitudinal vertical section of the cup, and

Figure 3 is a. vertical section through the centre of the feeding-cylinder used in the cup, and

Figure 4 a-view'ei` it detached.I l'

My invention relates to that class of seeding-machines in whichl the grain passes fromahopper into cups` underneath, and from which it is fed out by means of a small rotating cylinder located in each cup, there being a cup and cylinder placed under each opening in thehopper, of which there may be any desired number.

My improved cup consists of a. thin shell of cast iron, cast in two parts, one ofwhich-is represented by A, fig. 2, the same being a side view looking against its 'inner' face. These parts are cast'with projections, c, at their inneredge, through which holes are made to receive a. screw or rivet, as shown in fig. 1, these screws thus serving to unite the two parts of the shell'or cup firmly together. The form of the cupl longitudinally is represented clearly in iig. 2, and its form transversely by iig. 1. This cup is provided with lateral flanges, a, at its`upper edge, by which it is secured to the hopper. It is also formed with a hole, C, through each side, as shown in iig. 2, and around this hole, on the inner face of the shell, on each side, is aprojecting rim, e, as shown in figs. 1 and 2.' The shell is open at the top, and has a circular opening, D, at its rear end, as shown in g. 2.

- The cylinder B is formedwith radially-projecting ribsior teeth, o, on its periphery, they being rounded on their outer edges, as represented in tig. 3, and extending in an oval or circular outline from one side to the vother, as shown in g. 4. This cylinder is cast in two halves, united by short pins, z', projectinglfrom the face of one half, and fitting into corresponding holes, d, in the adjoining face of the other half, the parts being .shown united in iig. 1. 'I

On each'end, the cylinder B is provided with avhub, n, of proper size to fit in theholes C in the sides of -tlie cup A, the cylinder being hollow, and having adequate hole, I, extending through the hub on each side longitudinally, as representedA in figs. 1 and 3, to permit a shaft to be passed through them, and by whichthey are to be rotated.

It will be observed that. when the cup A and cylinder are thus constructed and placed together, as-

represented in iig. 1, there will be a considerable space leftibetween the inner faces ofthe cup or shell A and the ends of the ribs o on the cylinder, the special object of which is to prevent the 'grain from being crushed between them, as is apt to be the case in machines of this'class, as ordinarily constructed. l

A series of these cups, with their cylinders in, is secured to the under side of the hopper, and a square rod isv inserted through the entire series of cylinders, the rod being connected, by anysuita-ble gearing, with oue of the Wheels of the machine, which thereby causes all the cylinders to rotate with uniformity, thus feeding the grain out at the rear opening, D, in a continuous'and regular" stream, the circular form of the ribs o andthe circular opening D causing the grain to be delivered in an even stream, and thus etfectually prevepting bunching, as it is termed, or delivering` the grain in successive bunches or heaps. i l' It is obvious that these cups andlcyinders may be used to feed the grain upon a scattering-board for or gate inthe hopper-bottom.

broad-cast seeding, or into drill-tubes fer seeding in drills. The ow of the seed is to be rcgulatedzby n. Vslide yBy this method of constructing the cups und cylinders, I am enabled to make e seeding-machine thai; operates in a. most perfect and se-tsfectory manner.

Having thus described myV invention, what I claim, is 1.` The Vcup A, formed substantially as described, with the inwardly-projecting langes e on the inner` fec'e "of its sides, as set fotli. l

' 2. In combination with the cup A, the cylinder B, so constructed as to lcaye a space between its rbs o andthe sides of'V the' cup, to prevent the crushing of the grain, as described.
